I have 5 khakis, but a couple are getting snug.
Shirts, I've got 13, though 1½ don't count. One I realized was far too low cut to be worn at work after I bought it, low enough cut I'd have to put my name badge on my nipple. The other is a very nice button down shirt I bought when I thought I had landed another job; I can wear it if I want, but it's nice enough I shouldn't be wearing it if I might have to carry something dirty or cleaning up food off the carpet.
The nice thing about the shirts is that they range in color from deep burgundy to tomato/cinnabar, so some have a chance of surviving the post-Target closet cleaning.
